The change in c423d0e8a124 ("testing: Fix race in tnc/tnccs-20-pdp-pt-tls
scenario") is not really ideal as now the vici plugin might not yet be
ready when `swanctl --load-creds` is called.  Perhaps starting charon
before Apache causes enough delay.

Once we switch to charon-systemd this isn't a problem anymore as starting the
unit will block until everything is up and ready.  Also, the individual
swanctl calls will be redundant as the default service unit calls --load-all.
But start scripts do run before charon-systemd signals that the daemon is
ready, so using these would work too then.
